All ok.
But was difficult to find the right building inside the compound and for few days the host didn’t answer my messages.
Pocket WiFi was a good idea for travellers but was working intermittently and needed to be charged continually.
One day before leaving the reception wanted to checked my documents, asked me if I was the owner and told me something about new rules of the building. Seems like the apartment can’t be rented out. They wanted me to sign a document in Thai but I refused, anyway seemed not a big deal and I left the day after without any problem.
